Decalcification of rats elbows

Hi all,
I work in a research lab, and one of our researchers would like to get in
contact with histologists who specialize in bone work. He is working on
rats elbows, and it is important that, when decaling and cutting, none of
the cartilage is removed from the bone.
I would appreciate advise from all of you experts out there.
